"I got nexplanon put it in to treat my heavy, painful, & length periods (anywhere from 7 - 30 days) that no pills helped. Can't have estrogen because of chronic migraines. Since getting it inserted in late July, I have had 4 weeks in which I didn't have the same heavy, painful periods 24/7 (It's late February now). I went to the ER twice for severe dehydration (I managed to not be anemic enough to require a blood transfusion) and received 2 liters of IV fluids each time. I was prescribed meclizine for the constant dizziness from both the hormones themselves AND the constant dehydration, and zofran for the constant nausea. At almost 8 months, it's coming out next week because my body is just deteriorating. Back to square one. Sigh."
